Relationship between volume and survival in closed intensive care units is weak and apparent only in mechanically ventilated patients.

Background: Recent studies have found an association between increased volume and increased intensive care unit (ICU) survival; however, this association might not hold true in ICUs with permanent intensivist coverage. Our objective was to determine whether ICU volume correlates with survival in the Spanish healthcare system.

Methods: Post hoc analysis of a prospective study of all patients admitted to 29 ICUs during 3 months.

Ward mortality after ICU discharge: a multicenter validation of the Sabadell score.

Background: Tools for predicting post-ICU patients' outcomes are scarce. A single-center study showed that the Sabadell score classified patients into four groups with clear-cut differences in ward mortality.

Objective And Design: To validate the Sabadell score using a prospective multicenter approach.

Prone positioning in acute respiratory distress syndrome: a multicenter randomized clinical trial.

Objective: We examined the effect on survival of prone positioning as an early and continuous treatment in ARDS patients already treated with protective ventilation.

Design And Setting: Open randomized controlled trial in 17 medical-surgical ICUs.

Patients: Forty mechanically ventilated patients with early and refractory ARDS despite protective ventilation in the supine position.
